Patent JP-S6269121-A (JP)
Title: Displacement detector
Inventor: AKIMOTO KAZUNORI
IPC: G01P13/04
Filed: 1985-09-24
Abstract: PURPOSE:To read below a scale with a high resolution by converting a relative position variation quantity to a scale which has been graduated at an equal pitch, to a signal being approximate to a sine wave of a 90 deg. phase difference. CONSTITUTION:On a scale (magnetized track) 1, (n) pieces of poles per one round are provided at an equal pitch, and a sensor 2 is constituted of a magneto-resistance effect (MR) element for detecting a variation of a magnetic flux of the magnetized track 1. When a DC power source is applied to these MR elements, a signal VA and VB of a 90 deg. phase difference being approximate to a sine wave are obtained in a terminal in accordance with a rotational angle. Also, a carrier signal generator 3 outputs two-phase sine wave signals VCsinomegat, VCcosomegat of a 90 deg. phase difference. Subsequently, an analog multiplier 4 multiplies the signal VA and the signal VCsinomegat and outputs a signal VM1, and in the same way, an analog multiplier 5 multiplies the signal VB and the signal VCcosomegat and output a signal VM2. Next, an analog adder 6 adds the outputs VM1, VM2 of these multipliers 4, 5, and obtains an output signal VP. Also, a phase difference measuring circuit 7 derives a phase difference of the output VP of the adder 6 and the signal VCsinomegat.

Title: Can opening forming method for top plate of can container and can opening
Inventor: TAKADA ATSUSHI
IPC: B21D51/38
Filed: 1986-09-05
Abstract: PURPOSE:To make the fixture of a mouthpiece strong and to better the appearance of the can opening by forming the inner curling part on the vertical rising cylindrical part provided on the top plate of the can and fixing a fixed mouthpiece with the outer bending of the curling part from the base end after the outer insertion of a fixed mouthpiece. CONSTITUTION:An annular recessed part 5 and vertical rising cylindrical part 3 are formed by a pressing on one part of the top plate 1 of a can and a circular hole 3b is opened by leaving the outer peripheral edge 3a on the apex face of the cylindrical part. In this case, some whirl stop projecting parts are formed on the annular recessed part 5. The inner curling part 7 is thereafter made after forming a precurl 7a on the outer peripheral edge 3a. A fixed mouthpiece 4 is then outer-inserted to this vertical rising cylindrical part and the whirl stop is performed by setting the whirl stop recessed part of the lower part flange of the mouthpiece 4 to the whirl stop projecting part of the annular recessed part 5. The inner curling part 7 is thereafter press-contacted to the upper end face of the fixed mouthpiece 4 with the outer bending of the inner curling part 7 from the base end 7b and the fixed mouthpiece 4 is fixed to the top plate 1. The insertion of the fixed mouthpiece 4 can thus be made easy, the winding end of the outer bent inner curling part is not exposed to the external part and the can opening of good external appearance can be made.

Abstract: PROBLEM TO BE SOLVED: To suppress the deviation of the hot-water temperature of a hot-water supply by interruptions to a reheating operation. SOLUTION: The switching timing of the gas flow is set up for coinciding between the starting point of the change of the hot water temperature of the hot-water supply by the start up of a circulating pump at the switching from the hot-water supply singular operation to the simultaneous operation of the hot-water supply and the reheating, and the starting point of the change of the hot-water temperature of the hot water supply by the switching of the gas flow. The gas flow is changed by adding a first compensating gas flow α1 canceling the component of changes by the change of the hot-water temperature of the hot-water supply by the turning on of the circulating pump and by the change of the hot-water of the hot-water supply by the increase of the as flow.  When the simultaneous operation of the hot-water supply and the reheating is changed to the singular operation of the hot-water supply, the gas flow switching timing is set up coinciding the starting points of the change of the hot-water temperature of the hot water supply by the stopping the circulating pump and by the switching of the gas flow. The gas flow is controlled changing the gas flow to the singular operation deducting with the amount of second correcting calories α2 canceling both of the change of the hot-water temperature of the hot-water supply by stopping the circulating pump and the change of the hot-water temperature of the hot-water supply by the change of the gas flow.

Abstract: PURPOSE:To produce black Fe3O4 simply and inexpensively, adding reducing iron powder to an iron sulfate-containing solution acidified with sulfuric acid, heating them in a reaction bath with introducing air to it stirring so that black Fe3O4 is formed directly. CONSTITUTION:A solution of iron sulfate acidified with dilute sulfuric acid is heated to 80-100 deg.C, excess reducing iron powder is added to it, air is introduced to it with stirring, and Fe3O4 is directly formed in the solution. In the operation, the reducing iron powder added acts as a neutralizing agent and promotes the reaction, however, the reducing powder itself is eluted in the solution, to form Fe3O4 precipitate by oxidation with air. The reducing iron powder is further eluted with liberated sulfuric acid formed by the oxidation, and the reaction is continued. Consequently, a point wherein the reducing iron powder is completely eluted is regarded as the end point of the reaction.

Title: Character recognizing system
Inventor: KOIZUMI JUNICHI
IPC: G06K9/46
Filed: 1986-09-05
Abstract: PURPOSE:To realize at high speed the forcible separation of a recognition object character and its adjacent character, by extracting the right and left or the upper and lower contour information from contour information of only the stroke of the recognition object character, and executing a character recognition. CONSTITUTION:After the continuity of a segment from the upper and lower contour information or the right and left contour information extracted first is checked, discontinuous segments C-2, C-3 are eliminated from the contour information, and from the upper and lower contour information (or the right and left contour information) which becomes only the stroke of a recognition object character, the right and left contour information (or the upper and lower contour information) required for recognizing a character is generated without executing an image access. Thus, since the stroke of the recognition object character on an image after the first extraction becomes unnecessary, a part or the whole of the stroke of the recognition object character can be eliminated in preparation for the recognition of the next adjacent character.
